A 35-year-old Uzbek woman was injured after being allegedly stabbed by three Afghan nationals, including a 15-year-old girl, in southeast Delhi's Lajpat Nagar area, apparently over an "illicit" relationship, Indian police said on Tuesday.

The victim, Zarina, was stabbed on Sunday night by the minor and two of her male friends, identified as Abdullah and Shorab, aged 27 years, a senior police officer told the Hindustan Times.

"The dispute allegedly originated over Zarina informing her friend Roshini about her (Roshini's) husband's illicit affair with the minor. The 15-year-old got to know about Zarina's involvement and roped in two of her friends and attacked Zarina," he said.

Police said Zarina was admitted to hospital and is out of danger.

When the minor was escaping in a car with the accomplices, a passerby saw them and thought that the girl had been kidnapped by the men, according to police.

He made a call and police intercepted the vehicle on Lala Lajpat Rai Marg, said the officer.

It was later found during interrogation and through a series of calls that they were involved in a case of stabbing and the girl had not been kidnapped, he added.
